Before you power on your Trezor for the first time, take a few minutes to inspect the package thoroughly. Verifying your device’s authenticity is not optional — it is the first security step in your self-custody journey. A genuine, untampered Trezor is the foundation that every other security measure builds on. This guide walks you through exactly what to look for and what to do if something seems off.
Never use a Trezor purchased second-hand, received as a gift from an unknown source, or acquired from an unofficial reseller. Pre-owned devices may have been seeded with a compromised recovery phrase, allowing a previous owner to drain your funds at any time. Purchase only from trezor.io or an authorized reseller listed on the official site.

​
What’s in the Box

Every Trezor ships with the same core contents, regardless of model. Open your package on a clean, flat surface and confirm all of the following items are present:
  • Trezor hardware wallet — the device itself, sealed inside an inner cardboard sleeve
  • USB cable — USB-C for Model T and Model T Plus, Micro-USB for Model One
  • Recovery seed cards — two or more blank cards for writing down your seed words
  • Stickers — official Trezor stickers included as a small bonus
  • Quick-start booklet — a printed guide pointing you to trezor.io/start
  • Holographic security seal — applied to the device’s inner sleeve or outer box flap
If any item is missing, contact Trezor support at trezor.io/support before proceeding.

​
Verify the Holographic Seal

The holographic security seal is your first line of defense against a tampered device. Trezor applies this seal to the inner packaging to show whether the box has been opened after leaving the factory. Inspect the seal under good lighting. A genuine seal displays a shifting, iridescent holographic pattern. It should be fully intact with no lifting edges, tears, punctures, or residue indicating it was previously removed and re-applied. If you see any of these warning signs, do not use the device.
A missing or damaged holographic seal does not always mean a device is compromised — seals can occasionally be damaged in shipping. However, treat any seal irregularity as a serious concern and contact Trezor support immediately before continuing setup.

​
Verify Device Authenticity at Trezor.io/Start

Trezor builds a cryptographic authenticity check directly into the setup process. Follow the steps below to run it.
1

Navigate to trezor.io/start

Open your browser and go to trezor.io/start. This is the only official starting point for device setup. Bookmark it to avoid phishing sites that mimic the page.
2

Download and open Trezor Suite

Follow the prompt to download Trezor Suite for your operating system. Install it, then launch the application. Trezor Suite communicates with your device over a secure, encrypted channel.
3

Connect your Trezor

Plug your Trezor into your computer using the included USB cable. Trezor Suite detects the device and immediately begins an automated authenticity check. This check verifies a cryptographic signature stored in the device’s secure element — it cannot be faked by a counterfeit device.
4

Review the authenticity result

Trezor Suite displays a clear pass or fail result. A passing result confirms that your device is genuine and has not been tampered with at the firmware level. A failing result means you should stop immediately and contact Trezor support.
5

Proceed to firmware installation

Once authenticity is confirmed, Trezor Suite will prompt you to install the latest firmware. Brand-new Trezor devices ship without firmware as a deliberate security feature. Proceed with the installation — it takes under two minutes and completes entirely on-device.

​
Understanding the “No Firmware” Message

When you connect a new Trezor, the device screen shows a message indicating no firmware is installed. This is intentional and expected. Shipping devices without firmware ensures you install signed, verified code directly from Trezor’s servers the moment you set up your device — eliminating any opportunity for pre-installed malware.
After completing the unboxing and verification steps, move on to Install Trezor Suite for a full walkthrough of the app’s features, or jump straight to Create Your Wallet if Suite is already installed.
